there is actually NO way to safely do this unless you have been on the birth control pill for at least a month and only if its safe to skip the sugar pills of that particular brand of pill, thus skipping your period and getting it later on. you need to talk to a doctor about going on birth control and its presciption only and there are many side effects, anything else you might hear that can stop it will probably damage your health and arnt worth it.if your asking how to stop it now (while your on it) or soon, sorry but youll just have to deal with it. you can only stop it safely while on the pill
Birth control can temporarily stop your periods, but you have to be on it for a while to help. Also using birth control to stop your period, can have a lot of side effects, such as throwing off your cycle totally.
If you do want to use it to stop your cycle, speak to your doctor or pharmacist and ask them about the side effects.
